An inner wall grinding device regardless of the length of the pipeline

Abstract

The invention relates to the technical field of pipeline inner wall polishing, and discloses an inner wall polishing device ignoring the length of a pipeline. The inner wall polishing device solves the problems that different polishing heads need to be replaced when steel pipes with different hole diameters are processed, and the equipment has high cost, a plurality of spare parts of the polishingheads and low productivity; and the inner wall polishing device solves the other problems that inner and outer round polishing equipment only aims at the pipe ends of the steel pipe ends, the equipment is not prone to operating when the inner walls of the longer steel pipes and the shorter steel pipes are cleaned, the length of drive rods needs to be replaced continuously. The inner wall polishing device polishes the inner wall of the pipeline through two sets of polishing heads, threads of a connecting rod which is connected into a second polishing head are arranged as first sliding notches,while the first sliding notches are in tilting state, a connecting rod and a fixing rod which are is connected inside a first polishing head are in an existing inclined state. Therefore, when the second polishing head rotates, the first polishing head rotate in the formed direction of the notches; and the two sets of polishing heads rotate in opposite directions by arranging different thread lines.

Description

technical field [0001] The invention relates to the technical field of pipe inner wall grinding, in particular to an inner wall grinding device regardless of the length of the pipe. Background technique [0002] Steel pipes must be used in construction. For example, in hydropower stations, pipes are used to transport liquids. Due to the humidity in the air, metal pipes without anti-corrosion treatment are prone to corrosion and rust during long-term use, which makes the transported The liquid is mixed with various impurities, which will affect the running accuracy of the machine, and even cause the machine to malfunction in severe cases. Therefore, it is extremely important to spray paint anticorrosion treatment and rust removal on the inner wall of the metal pipe. However, due to the special working space limitation, the above work is difficult to be completed manually, and it is necessary to develop a corresponding paint anticorrosion and rust removal device for the inner ...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an inner wall grinding device that ignores the length of the pipeline, which solves the need to replace different grinding heads when processing steel pipes with different apertures, and the equipment has high cost, many grinding head spare parts, and low productivity; The other is the inner and outer circle grinding equipment only for the end of the steel pipe, and it is not easy to operate when cleaning the inner wall of the longer and shorter steel pipes, and the length of the drive rod needs to be changed continuously
